Ideally, these wouldn't depend on an external
i variable.

Maybe something like:

#define seq_putx(m, message, size, var) \
do { \
	int _i; \
 	seq_printf(m, message);	\
 	for (_i = 0; _i < (size - 1); _i++) \
 		seq_printf(m, "%02x:", var[_i]); \
	seq_printf(m, "%02x\n", var[_i]); \
} while (0)

Maybe later change these to use the recently introduced
seq_hex_dump: https://lkml.org/lkml/2014/7/11/269
